- Collision prevention often comprises automatic emergency braking systems of different kinds, and for such a system it is of interest to avoid unnecessary automatic braking situations, presumably due to a false alarm, since this causes both distress of a driver, and also a possibly dangerous traffic situation, for example with respect to vehicles behind the braking vehicle.
- EP 1577682 discloses a lane change detection system, but there is a need for a device and a method for a faster and more accurate detection of if a vehicle in in front of, and in an adjacent lane of, a detecting vehicle suddenly moves into the same lane as, and in front of, the detecting vehicle. In this way, unnecessary safety actions, such as emergency braking, may be avoided.

Such a closest point is detected by analyzing the tangential rate of reflected radar signals in a previously known manner.
- the target vehicle rectangle 22 comprises a first boundary k and a second boundary 11, the boundaries k, 11 defining the largest extension of the target vehicle rectangle 22 as viewed from the radar transceiver 3 in the azimuth plane, in other words the largest width of the target vehicle rectangle 22 as viewed from the radar transceiver 3.
- the target vehicle rectangle 22 further comprises a first corner j which is defined by the point of the target vehicle rectangle 22 that is closest to the radar transceiver 3, the first corner j being positioned along a first bearing 12 corresponding to a first azimuth angle ⁇ 1 with reference to the front line 6.

- a difference angle ⁇ 2 denotes the difference between the second azimuth angle ⁇ 1 + ⁇ 2 and the first azimuth angle ⁇ 1 .
- a first distance jm is defined between the first corner j and a first end point m; a second distance kl is defined between the first boundary k and a second end point 1; and a third distance jn is defined between the first corner j and a third end point n. Furthermore, there is a fifth end point i in the middle of the front of the vehicle, at the front aperture of the radar transceiver 3, where all end points m, 1, n, i lie on the front line 6.
- the first distance jm and the second distance kl are always parallel to the target vehicle's initial forward running direction 23.
- the third distance jn is always parallel to the target vehicle's present forward running direction 23, 23' 23"; the target vehicle's forward running direction changing when the target vehicle 8 changes travel direction.

- the target vehicle 8 has performed a change of travel direction with a second target velocity v' t , which will result in a change of lane from the second lane 9 to the first lane 7, where the target vehicle 8 will cut in in front of the present vehicle 1.
- This is detected by the present vehicle's radar system 2 where a first corner j', which has now changed relative Figure 2 , is positioned along a first bearing 12', having a first azimuth angle ⁇ ' 1 .

Due to ordinary angular mathematics and trigonometric, there is a fifth azimuth angle n/2 - ⁇ ' 1 formed between the extensions of the eighth distance i'j' and the first distance j'm', and a sixth azimuth angle ⁇ - ⁇ ' formed between the extensions of the eighth distance i'j' and the third distance j'n'. The first yaw angle ⁇ A is formed between the first distance j'm' and the third distance j'n'. It is evident that the sixth azimuth angle ⁇ - ⁇ ' equals the sum of the fifth azimuth angle n/2 - ⁇ ' 1 and the first yaw angle ⁇ A .
- the first distance j'm', the second distance k'l', the fourth distance i'l' and the fifth distance i'm' may be calculated.
- the seventh distance i'k' and the eighth distance i'j' are calculated. Then the seventh distance i'k', the eighth distance i'j' and the difference angle ⁇ ' 2 are used to calculate the ninth distance j'k' by means of the cosine rule. Having these data, the ninth distance j'k', the seventh distance i'k' and the eighth distance i'j' are used to calculate the third azimuth angle ⁇ ' by means of the cosine rule.

- yaw rate includes yaw speed and/or yaw acceleration. Generally, a yaw movement is calculated.
- the second boundary 11' could be used instead of the first boundary k'. Then the fourth azimuth angle ⁇ would have to be formed and calculated for a bearing extending towards the second boundary 11' instead. It would also be necessary to compensate such that the target vehicle's present forward running direction 23' is headed correctly.
- the present vehicle 1 comprises an emergency control unit 14 and safety means 15, 16, in this example an emergency braking system 15 and an alarm signal device 16, all these only being indicated in Figure 1 for reasons of clarity of the drawings.

- the target vehicle 8 is continuing with its lane changing maneuver, having a third target velocity v'' t , the target vehicle 8 now clearly cutting in in front of the present vehicle 1.
- This is detected by the present vehicle's radar system 2, where a first corner j'', which has now changed relative Figure 3 , is positioned along a first bearing 12'', having a first azimuth angle ⁇ '' 1
- a first boundary k'' which has now changed relative Figure 3 , is positioned along a se3cobnd bearing 13'', having a second azimuth angle ⁇ '' 1 + ⁇ '' 2 .
- End points i'', l'', m'' and n'' are formed in the same way as before, as well as azimuth angles ⁇ '', ⁇ '', n/2 - ⁇ '' 1 , n - ⁇ '.
- the target vehicle 8 has been shown as positioned in front of and laterally displaced relative the radar system 2. However, generally, the target vehicle 8 is longitudinally and laterally displaced relative a detection system 2.
- the present invention also relates to a method for a vehicle safety system comprising the steps:
- the emergency braking system may be in the form of a vacuum emergency brake or a brake assist device.
- the microwave parts of the radar system 2 are assumed to be of a previously known design, and the radar system 2 comprises more parts than shown, for example transmitting and receiving antennas.
- the radar system 2 may furthermore comprise a number of other parts.
- the detection system 2, the emergency control unit 14 and the safety means 15, 16 are comprised in a vehicle safety system 17.
- the radar transceiver 3 is arranged to send and receive radar signals 5 at different azimuth angles ⁇ in an azimuth plane with reference to the front line 6.
- the detection system 2 is arranged to send and receive detection signals 5 at different azimuth angles ⁇ in an azimuth plane with reference to a first reference line 6.
- the yaw angles ⁇ A , ⁇ B are in the examples formed between a present forward running direction 23', 23'' and the initial forward running direction 23.
- the yaw angles ⁇ A , ⁇ B are formed between a second reference line and a third reference line, where the third reference line differs from the second reference line by the yaw angle. This means that the third reference line changes as the forward running direction changes, but not the second reference line.
- the second reference line is for example set at certain times, and when a yaw movement is detected, the last second reference line that has been set is used.
- the term initial when relating to the forward running direction 23 is referred to a set running direction that is used for calculating the yaw angel.
- the second reference line is constituted by the extension of the initial forward running direction 23 and the third reference line is constituted by the extension of the present forward running direction 23, 23', 23''.
- the third reference line should differ from the second reference line by the yaw angle.
- the target vehicle 8 has mainly been traveling in the same direction as the present vehicle 1, but it is conceivable that the target vehicle 8 mainly is travelling towards the present vehicle 1.
- the yaw angle is determined in a corresponding manner as for the case described where the target vehicle 8 mainly is traveling in the same direction as the present vehicle 1. It will be necessary to compensate such that the target vehicle's present forward running direction 23' is headed correctly.
- the present invention can be applied to target vehicles at orientations different than target vehicles mainly travelling in the same direction as a present vehicle such as for example crossing or oncoming target vehicles.
- the present invention relates to a vehicle safety system comprising a detection system 2, an emergency control unit 14 and safety means 15, 16.
- the detection system 2 is arranged to detect a target vehicle 8 positioned longitudinally and laterally displaced relative the detection system 2.
- the vehicle safety system is arranged to be comprised in a present vehicle.
